Type of parasites in the human body

Parasites that can live in the human body, is so much. They are found all over the world, but the most common of these is worms, parasitic in the human intestine (worms). However, parasites can live in the human body almost anywhere: lungs, liver, brain, eyes, skin, etc.



Pinworms – the best known human parasites that live in the intestine. The disease, which causes of pinworms is called the "enterobioz". It affects not only people, but monkeys. Increased risk of infection Ostricami children are. According to various sources, the level of their participation in the enterobioz school age is 25 to 90%.

Pinworms are transferred from one person to another. Contamination occurs via the hands, clothing, and other items that touched a sick person, provided that, after contact was made, wash your hands, and the eggs of pinworms coming out of his mouth (this is especially true during the meal). Transfer the eggs of these worms, nematodes to flies and cockroaches, obsemenyaya their food. Pinworms live in the small intestine, cecum, colon. They mate in the ileum, after which the woman through the rectum crawls out of the anus and lays eggs in the anus.

Enterobioza symptoms are itching in the anal region, intoxication of the organism (allergic reactions, exhaustion, fatigue), anemia, increased eosinophils in the blood, insomnia, pain in the abdomen.

To avoid reinfestation, it is important to keep your hands clean, wash them after visiting any public places, after using the toilet, before eating, etc. Nails must be cut short, carefully disinfect bedding and underwear, do daily wet cleaning in the apartment.


Toksokara is a parasite of the group of the nematodes. The disease, which causes Toksokari is called "Toksokaroz". This attack, a person may be the larvae (visceral and ocular) and intestinal. The disease is widespread all over the world.

Toksokaroi infection occurs by ingestion of eggs of worms in human digestive tract. This most often occurs when eating food or water contaminated with the feces of dogs. No less dangerous contact with the sick animals. Natural media Toksokar are cats and dogs, foxes and wolves. Once in the human body, the larvae, the worm wanders through the blood vessels, and it can settle into any organ. It depends on the symptoms of the disease.

Toksokaroz most often manifested in the form of allergic reactions (angioedema, skin rash, asthma). During exacerbations there may be an increase in body temperature to 38 degrees, but the symptoms of poisoning in this poorly expressed. The suspect Toksokaroz can be enlarged lymph nodes.

Toksokaroza visceral form is the most common, occurring in lesions of the internal organs (intestines, respiratory organs, heart valves). A person may experience abdominal pain in the right hypochondrium, dyspepsia, nausea.

With the defeat of breathing organs in humans are shortness of breath, dry cough, asthma.

If Toksokari land of the heart valves, the patient has weakness, bluish discoloration of the fingers and in the nasolabial triangle, shortness of breath.

The skin in the form characterized by itching, feeling the stirring beneath the skin, inflammation of skin and mucous membranes.

If the neurological form of the parasite triggers the development of inflammation of the meninges and brain tissues. This manifests itself in headaches, nausea and vomiting, convulsions and other neurological disorders.

The human Ascaris is a round worm, parazitiruyushim the small intestine. The disease, which causes these parasites, called "ascariasis".

Master of roundworm, and the source of infection is a sick man. Together with its feces on eggs of worms enter the soil, where they Mature the larvae. Then this soil is transferred to the food or hands of man, and poor personal hygiene and poor handling of fruits, vegetables and berries – digestive tract. Still infection the most disadvantaged children and rural residents.

Ascariasis occurs in different stages of their development in different ways. Stage of larval migration through the body, is an increase in body temperature, dry cough, rales in lungs, increase in size the lymph nodes. Children suffering from ascariasis more difficult than for adults. The characteristic symptoms of ascariasis are allergic skin reactions.

When the parasitism of the intestine, the patient developed dyspepsia, diarrhoea replaced the constipation, often with abdominal pain, nausea and vomiting. The nervous system is observed in hysterical fits, insomnia, mental fatigue, headache.


Ancylostoma and necator are two species of roundworms belonging to the family Ancylostomatidae and cause a disease called "ankilostomidoz".

There are two ways of infecting the human body of these parasites is fecal-oral (contaminated water, fruits, vegetables) and skin contact with soil (infiltration occurs through the skin).

Clinical symptoms ankilostomidoza: papular-vezikulyarnie rash, shortness of breath and cough, loss of appetite, nausea, abdominal pain, diarrhea, anemia iron deficiency.


A tapeworm refers to the cestodes team Pseudophyilidea. These parasites live in the small intestine of man and mammals that consume fish. Intecomin infection provokes the development of diseases, such as difillobotrioz. There are 12 types of tapeworms that can parasitize the human body, however, the most common is the tapeworm.

Infection occurs by eating uncooked raw or salted fish and caviar, which contains the worm eggs.

Symptoms the presence of parasites in the intestine: nausea, abdominal pain, anemia. In severe cases developing intestinal obstruction.

Beef tapeworm (tapeworm)

Beef tapeworm is a tape worm which belongs to the family of seven. The larvae affect the livestock and stage of the tapeworm lives in the human body (the intestines). Sample provokes a disease called "beef tapeworm infection", usually the patient is one of the parasites.

Human infection occurs through the digestive tract after eating poorly thermally processed meat (beef).

Clinically the disease is manifested by nausea, excessive appetite, abdominal pain, unstable stool, allergic reactions type of hives.

Pork tapeworm

Pork tapeworm refers to parazitiruyushim tapeworms that infect mammals animals. The intermediate carriers can be pigs, dogs, rabbits, camels, but the target host is always the people. If the human body detected in adult parasites, we talk about this illness, such as tenioz. When the parasite is in the patient's body of the larvae, the disease is called "cysticercosis".

Pork tapeworm infection occurs by eating raw meat of pigs. Sometimes sources cysticerci are obsemenennie hands or water. The patient teniozom represent epidemiological risk itself (infestation of maggots in the brain, skin, eyes or skeletal muscles) and others.

Tenioza symptoms: abdominal pain, appetite loss, irregularity, headaches, frequent dizziness, fainting (very dangerous tenioz the brain and eyes).



Echinococcus is a tape worm from team ciklofillid. Adults are parasitic in the intestines of dogs and cats, events, jackals and wolves. People for the larvae of the parasite, which can cause serious illness – echinococcosis.

The larvae can infect the internal organs, forming them ehinokokkovie cysts. People echinococcal acting as intermediate hosts. Infection by contact (the process of butchering, the interaction with sick animals) or alimentary infections (when used obsemenennoi food or water). At risk are people who engage in agriculture or have permanent contact with animals.

Symptoms can occur for many years. When the asymptomatic stage ends, the status of the introduced larvae, there can be pain, itching, possible symptoms of hives. Also affect the functioning of the body, inside of which parasitize the larvae of Echinococcus. Increase in body temperature and fever has been detected suppuration of the cyst.


Alveolar is gelmintom from the group of cestodes. Worm shouts a threat to human life alveokokkoz disease, which is characterized by the formation of the primary tumor in the liver later, the spread of metastases to other organs.

Infection occurs by ingestion of the mouth of the oncospheres of the parasite. This can happen during a hunt, the process of butchering wild animals, contact with Pets, eating raw berries and herbs from the forest.

Symptoms alveokokkoza reduce the pain in the right hypochondrium, belching, nausea. There is often itching, allergic reactions. It is not excluded, suppuration of the tumor, where the parasite and its breakthrough in the peritoneal or pleural cavity. Metastases of the alveoli can be detected in the brain and in the lungs.



Giardia (another name giardi) is a parasite genus of flagellates related to the order of diplomonadid. Giardia provoking a disease called "giardiasis" and parasites in the small intestine of humans and many other mammals, creatures, and even birds.

Lyambliyami infection occurs fecal-oral: food, water and contact-household way. The maximum value of transmission is the consumption of raw water, contaminated food, use of public items, obsemenennih cistami Giardia.

The leading symptoms of giardiasis are nausea, abdominal pain, disorders of stool, excessive flatulence. In addition, patients suffering from allergic reactions, poisoning, and neurotic disorders.

Histological amoeba

Histological amoeba is protozoinii parasite that causes a disease called "amoeba disease". The disease manifests itself in the formation of ulcers in the colon later the defeat of other internal organs.

Amoebic infection occurs fecal-orally, while the Mature cysts in water or food belonging to the gastro-intestinal tract of humans. Possible connection to transfer the parasite through unwashed hands. Carriers of the amoebas can be used to fly. The second method, the distribution of amebiasis is sex (anal sexual intercourse).

Symptoms of amoebiasis: abundant mucous stools, abdominal pain, blood in the stool, weight loss, anemia. In addition, extraintestinal amebiasis is characterized by the formation of abscesses in those organs, which affect the parasite (lungs, brain, liver, etc.).


The disease is called "Gnatostomoz" caused by the larvae and adults of the nematode Gnathostoma spinigerum.

Infection occurs by eating raw meat, fish, frogs or birds, and by drinking not boiled water is not disinfected.

Symptoms of cough and pain in the site of entry of larvae under the skin, local inflammation and fever. Characterized by severe swelling and itching. As a rule, a week after the manifestation of symptoms disappear, but recur again for many years. A dangerous loss of the eyeball and the brain, it often ends in death.



Trichinella are parasitic round worms, whose larvae live in the muscles (extraocular, mastication organs, muscles and diaphragm), and into adulthood – the lumen of the small intestine. The disease, which causes Trichinella, called "trichinosis." It is a killer.

Human infection occurs by eating raw or poorly processed meat of wild and domestic animals.

The symptoms of these diseases include loss of appetite, vomiting, diarrhea and abdominal pain. Later joined by muscle pain, swelling of the eyelids, skin rash, increased body temperature to 40 degrees.


Shistosoma are worms, flukes of the genus of trematodes. They provoke a disease called "schistosomiasis". Human infection occurs during bathing, in the process of washing clothes or watering the land with water, the larvae shitosom. They can penetrate the human body, even through the holistic the skin and mucous membranes.

Symptoms in the acute phase of the disease manifests itself, that the temperature rise of the high marks, itching and appearance of papules all over the body. When the disease enters the chronic phase, the infected may be signs of vaginitis, prostatitis, colitis, ascites, hydronephrosis, etc.

Parasites that can cause harm to the human body, is so much. Most of them penetrate into the body of their host through the gastrointestinal tract when non-technical safe cooking and follow basic hygiene procedures.
